Description

Technical Field

[0001] This utility model belongs to the field of pulverizing technology and relates to a blade wet grinding pulverizer. Background Technology

[0002] In the traditional grinding process of granular materials (such as soybeans, mung beans, rice, glutinous rice, etc.), a small gap (usually finely adjusted at around 1 mm) is maintained between the two grinding discs to achieve effective crushing and grinding. However, this gap design has some problems. On the one hand, if the gap is too small, the material flowability becomes poor. Although the grinding fineness becomes smaller, the efficiency is greatly reduced. Due to long-term use and wear, the two grinding discs may gradually deform due to uneven wear, resulting in uneven fineness. It may even lead to direct contact between the grinding discs, causing equipment damage or poor grinding effect. On the other hand, if the gap is too large, the fineness of the material may not meet the requirements, resulting in low operability. Utility Model Content

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1-6 As shown, this utility model is a blade wet grinding mill, including a support 1 and a rotating shaft. A lower base plate 3 is welded to the support 1. A motor 2 is installed at the lower end of the lower base plate 3, and a ring 15 is welded to the upper end. An upper support plate 5 is welded to the upper end of the ring 15. A sealing cover plate 6 is connected to the upper end of the upper support plate 5 by a fulcrum clamping bolt 10. The sealing cover plate 6, the upper support plate 5, the ring 15 and the lower base plate 3 together form an inner cavity. A screw feeder 8, a moving and fixed grinding mill 11, a blade 12, a blade 13 and a filter screen 4 are arranged in sequence in the inner cavity. The filter screen 4 divides the inner cavity into a grinding zone and a cavity zone. The moving and fixed grinding mill 11 includes a moving grinding mill 111 and a fixed grinding mill 112. The screw feeder 8, the moving grinding mill 111, the blade 12 and the blade 13 are connected and fixed to the shaft of the motor 2 by a spline connection of the rotating shaft. A hopper 7 is installed on the upper end of the sealing cover plate 6, and an annular water inlet 9 is provided on the outer side of the lower end of the hopper 7; a fixed roller 112 is provided on the outer side of the moving roller 111 for use, and the fixed roller 112 is installed on the lower end face of the sealing cover plate 6. A discharge port 14 is provided on the bottom plate 3, and the upper end of the discharge port 14 communicates with the cavity formed by the filter screen 4 to discharge the filtered material.

[0021] Material flows downward from the hopper and is quantitatively fed into the inner cavity by the screw feeder 8. The moving millstone (111) works in conjunction with the stationary millstone (112) to crush and pulverize the material. Blades (12) and (13) are used to further cut and pulverize the material to achieve a fine crushing effect. The material is graded by the filter screen (4) inside the inner cavity. Material that is not completely crushed continues to be repeatedly processed by the blades, ultimately completing the wet grinding and pulverization process. At the same time, the annular water inlet 9 is connected to a water tap to cool the material in the cavity and provide flowability. Finally, the material that has been crushed and treated with water is discharged from the outlet 14 after being screened by the filter screen 4, effectively improving the efficiency and quality of material processing.

[0022] Preferably, the filter screen 4 is connected to the lower base plate 3 through small pillars arranged in a circle. The lower end of the small pillars is welded to the lower base plate 3, and the filter screen 4 is fixed to the upper end of the pillars by screws. After removing the screws, the filter screen 4 can be replaced or cleaned.

[0023] Preferably, the upper support plate 5 is provided with four or more fulcrum clamping bolts 10 to clamp and lock the sealing plate onto the upper support plate 5. Loosening the fulcrum clamping bolts 10 allows the sealing cover plate to be removed for cleaning and maintenance of the cavity.

[0024] Preferably, the blade assembly includes a first blade 12 and a second blade 13, which are arranged vertically. The diameter of the first blade 12 is smaller than that of the second blade 13, so as to cut and crush materials of different discrete ranges.

[0025] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
